Overview of IEC 60896-22
Sep 13, 2022

This part of IEC 60896 applies to all stationary lead-acid cells and mono-bloc batteries of the valve regulated type for float charge applications, (i.e. permanently connected to a load and to a DC power supply), in a static location (i.e. not generally intended to be moved from place to place) and incorporated into stationary equipment or installed in battery rooms for use in telecom, uninterruptible power supply (UPS), utility switching, emergency power or similar applications.


The objective of this part of IEC 60896 is to assist the specifier in the understanding of the purpose of each test contained within IEC 60896-21 and provide guidance on a suitable requirement that will result in the battery meeting the needs of a particular industry application and operational condition. This standard is used in conjunction with the common test methods described in IEC 60896-21 and is associated with all types and construction of valve regulated stationary lead-acid cells and mono-blocs used in standby power applications.


Terms and definitions:

Accuracy (of a measuring instrument)

Quality which characterizes the ability of a measuring instrument to provide an indicated value close to a true value of the measure

Accuracy class

Category of measuring instruments, all of which are intended to comply with a set ofspecifications regarding uncertainty

Ambient temperature

Temperature of the medium in the immediate vicinity of a cell or battery

Ampere-hour

Quantity of electricity or a capacity of a battery obtained by integrating the discharge current in ampere with respect to time in hours

Secondary battery

Two or more secondary cells connected together and used as a source of electrical energy

Monobloc battery

Secondary battery in which the plate packs are fitted in a multi-compartment container

Floating battery

Secondary battery whose terminals are permanently connected to a source of constant voltage sufficient to maintain the battery approximately fully charged, intended to supply a circuit, if the normal supply is temporarily interrupted

Battery capacity

Quantity of electricity or electrical charge which a fully charged battery can deliver underspecified conditions

Charge

Operation during which a secondary battery receives from an external circuit electrical energy,which is converted into chemical energy

Full charge

State where all the available active material of a secondary cell or battery has been reconverted to its fully charged status

Overcharge

Continued charging after the full charge of a secondary cell or battery

Cell

Assembly of electrodes and electrolyte, which constitutes the basic unit of a secondary battery

Electrochemical cell

Electrochemical system capable of storing in chemical form the electric energy received and which can give it back by reconversion, i.e. a secondary cell

Secondary cell

Assembly of electrodes and electrolyte which constitutes the basic unit of a secondary battery

Valve-regulated cell

Secondary cell which is closed under normal conditions but which has an arrangement, which allows the escape of gas if the internal pressure exceeds a predetermined value. The cell cannot normally receive the addition of electrolyte

Actual capacity

Quantity of electricity delivered by a cell or battery, determined experimentally with adischarge at a specified rate to a specified end-voltage and at a specified temperature

Nominal capacity

Suitable approximate quantity of electricity used to identify the capacity of a cell or battery

Rated capacity

Quantity of electricity, declared by the manufacturer, which a cell or battery can deliver underspecified conditions after a full charge

Shipping capacity

Quantity of electricity, declared by the manufacturer, which a cell or battery can deliver, at the time of shipment, under specified conditions of charge

Durability

Ability of an item (battery) to perform a required function under given conditions of use and maintenance, until a limiting state is reached

Electrolyte

Liquid or solid phase containing mobile ions that render the phase electrically conducting

Stationary equipment

Either fixed equipment or equipment not provided with a carrying handle and having such amass that it cannot easily be moved

Failure

Termination of the ability of an item (battery) to perform the required function

Lead-acid battery

Secondary battery in which the electrodes are made mainly from lead and the electrolyte is asulphuric acid solution

Design life

Expected period of useful life of a battery according to components, design and application.
